Anhydrous Yttrium Chloride yog dab tsi?

Anhydrous yttrium chloride, nrog rau cov tshuaj formula YCl₃, yog ib qho tseem ceeb inorganic tshuaj compound.
Nws feem ntau yog dawb crystalline lossis hmoov hmoov. Hais txog nws cov qauv tshuaj, nws muaj yttrium cations (Y³⁺) thiab chloride anions (Cl⁻) tuav ua ke los ntawm ionic bonds. Lub yttrium atom nyob rau hauv lub compound muaj ib tug +3 oxidation xeev.
Los ntawm qhov kev xav ntawm lub cev, nws cov ntsiab lus melting yog nyob ib puag ncig 721 degree thiab nws qhov kub kub yog kwv yees li 1507 degree. Nyob rau hauv chav tsev kub, nws muaj qhov ceev ntawm 2.67 g / cm³. Thaum nws los txog rau solubility, anhydrous yttrium chloride qhia zoo solubility hauv dej, ethanol, thiab pyridine. Txawm li cas los xij, nws yog hygroscopic, txhais tau tias nws muaj lub siab nyiam nqus dej los ntawm huab cua. Thaum nws los rau hauv kev sib cuag nrog huab cua ntub, nws tuaj yeem nqa cov dej noo sai sai thiab tsim ntau yam hydrates uas nws cov ntsiab lus pes tsawg yuav tsis zoo - txhais.
Nyob rau hauv lub tshav pob ntawm chemical synthesis, nws ua hauj lwm raws li ib tug tseem ceeb precursor. Nws tuaj yeem siv rau hauv kev npaj ntawm lwm yam yttrium - muaj cov khoom sib txuas. Piv txwv li, nws yog ib qho khoom pib rau kev sib txuas ntawm yttrium - raws li cov ceramics, uas yog siv rau hauv ntau hom kub thiab hluav taws xob siv. Hauv kev tsim cov phosphorus, anhydrous yttrium chloride kuj tseem ceeb heev. Phosphors yog cov khoom siv uas tuaj yeem tawm lub teeb nyob rau hauv qee qhov kev xav tau, xws li hauv cov teeb fluorescent thiab cathode - ray tubes. Yttrium - raws li phosphors ua los ntawm anhydrous yttrium chloride tuaj yeem tawm lub teeb hauv cov xim sib txawv, nyob ntawm seb cov ntsiab lus doping thiab cov khoom siv tshwj xeeb.
Ntxiv mus, nyob rau hauv cov ntsiab lus ntawm metallurgy, nws muaj peev xwm ua si lub luag hauj lwm nyob rau hauv lub extraction thiab purification ntawm yttrium hlau. Los ntawm kev siv txoj kev txo kom tsim nyog, yttrium hlau tuaj yeem tau txais los ntawmanhydrous yttrium chloride. Yttrium hlau nws tus kheej muaj cov ntawv thov tseem ceeb hauv cov hlau, xws li siv los txhim kho cov khoom siv hluav taws xob thiab thermal ntawm lwm cov hlau.
